Answer:
There is more wood in a 60-foot-high tree trunk with a radius of 2.4 feet
Step-by-step explanation:
* Lets talk about the right circular cylinder
- It has two circular bases
- The volume of it = Area of the base × its height
- The area of the base = πr²
- The quantity of wood in the tree is the volume of the cylinder
* Lets calculate the volumes the two trees and compare
between them
- Volume of the first tree:
∵ Its radius = 2.1 feet
∴ The area of its base = π(2.1)² = 4.41π feet²
∵ Its height = 70 feet
∴ Its volume = 4.41π × 70 = 308.7π = 969.8 feet³
- Volume of the second tree:
∵ Its radius = 2.4 feet
∴ The area of its base = π(2.4)² = 5.76π feet²
∵ Its height = 60 feet
∴ Its volume = 5.76π × 60 = 345.6π = 1085.7 feet³
∵ 1085.7 > 969.8
∴ The volume of wood in 2nd tree > the volume of wood in 1st tree
* There is more wood in a 60-foot-high tree trunk with a radius of 2.4 feet

Answer:
-17/10 is 1.7 is a rational number
Step-by-step explanation:
In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number. ... Moreover, any repeating or terminating decimal represents a rational number.
Rational numbers are numbers that can be expressed as a fraction with an integer numerator and denominator, where the denominator isn't zero. -17/10 is a rational number because it fits this definition, as -17 is the integer numerator and 10 is the integer denominator.
Explanation:The number -17/10 refers to a specific type of number known as a rational number. Rational numbers are numbers that can be written as a fraction where both numerator and denominator are integers and the denominator is not zero. Therefore, -17/10 is indeed a rational number because it can be expressed as a fraction as the definition suggests. The numerator is -17 and the denominator is 10, both of which are integers and the denominator is not zero. Thus, when dealing with content-loaded rational numbers like -17/10, you can be confident that you are indeed working with a rational number.

A house worth $70,000 when purchased was worth $67,000 after the first year and $64,000 after the second year. If the economy does not improve and this trend continues, what will be the value of the house after 7 years? a) Write an explicit formula for the sequence. Explain where you found the numbers you are putting in the formula. b) Identify the value of n and explain where you found it. Use the explicit formula to solve the problem.
Answer:
a) The formula for the sequence is
[tex]a_n = 67,000 -3,000(n-1)[/tex]
b) [tex]a_7 = 49,000[/tex]
Step-by-step explanation:
Note that the difference between any two consecutive terms in the sequence is always equal to $3,000
[tex]67,000-70,000= -3,000\\\\64,000-67,000=-3,000[/tex]
Then we have an arithmetic sequence where each term increases by a magnitude of 3,000 with respect to the previous term.
The explicit formula for an arithmetic sequence is:
[tex]a_n = a_1 +d(n-1)[/tex]
Where d is the common difference between the consecutive terms of the sequence
[tex]d = -3,000[/tex]
[tex]a_1[/tex] is the first term, or the value of the house after year 1 [tex]a_1= 67,000[/tex]
n represents the number of years since the house was purchased
With
n={0, 1, 2, 3, 4, 5, 6, 7,.., n}
a) Then the formula for the sequence is
[tex]a_n = 67,000 -3,000(n-1)[/tex]
With
n={0, 1, 2, 3, 4, 5, 6, 7,.., n}
---------------------------------------------------------------------------------------------
b) Now we can use the formula to find the price of the house after 7 years
[tex]a_7 = 67,000 -3,000(7-1)[/tex]
[tex]a_7 = 67,000 -3,000(6)[/tex]
[tex]a_7 = 49,000[/tex]

P.S. posting all of the RSM questions aren't you
Answer:
The radius is 18 cm
Step-by-step explanation:
Given that a right triangle △ABC with right angle C is inscribed in a circle.
Also, AC = 18 cm, m∠B = 30°
we have to find the radius of this circle.
In ΔABC
[tex]\sinB=\frac{AC}{AB}=\frac{18}{AB}[/tex]
[tex]AB=\frac{18}{\sin 30}=\frac{18}{\frac{1}{2}}=36cm[/tex]
As given right angle i.e angle C is of 90° which is angle formed in the semicircle. Hence, the hypotenuse side must be the diameter of circle.
Diameter=36 cm
[tex]Radius=\frac{1}{2}\times diameter=\frac{1}{2}\times 36=18 cm[/tex]

3x+1+5x=7+15+7x what is x?
Answer:
x = 21Step-by-step explanation:
3x + 1 + 5x = 7 + 15 + 7x combine like terms
(3x + 5x) + 1 = (7 + 15) + 7x
8x + 1 = 22 + 7x subtract 1 from both sides
8x = 21 + 7x subtract 7x from both sides
x = 21
Answer:
X= 21
Step-by-step explanation:
First you want to add alike terms which will get you 8x+1=22+7x. Next you want to get your x on one side so I subtracted 7x which you get x+1=22. Last you want to get rid of your 1 to get x alone so you subtract 1 from both sides and you get x=21.

7 people share 3 cookies what part of a cookie does each person get
If 7 people share 3 cookies, a part of a cookie that each person gets is 3/7 cookies.
In Mathematics and Euclidean Geometry, a unit rate refers to the quantity of material that is equivalent to a single unit of product or quantity.
In this context, the unit rate can be calculated by using the following formula;
Unit rate = Total cookies/Total number of people
Unit rate = 3/7 cookies.
In this context, we can reasonably infer and logically deduce that the unit rate indicates 3/7 cookies per person.
Complete Question:

What are the slope and the y-intercept of a linear function that is represented by the table
Answer:
i think its the first one but i'm not sure
Step-by-step explanation:
Answer: The slope is [tex]\frac{-2}{5}[/tex] and the y-intercept is [tex]\frac{-1}{3}[/tex]
Step-by-step explanation:
We know that the intercept form of a linear function is given by :-
[tex]y=mx+c[/tex], where m is the slope of the line and c is the y intercept point.
The slope of a function is given by :-
[tex]m=\dfrac{\text{change in y}}{\text{change in x}}\\\\\\\Rightarrow\ m=\dfrac{\frac{-2}{15}-\frac{-1}{30}}{\frac{-1}{2}-\frac{-3}{4}}\\\\\\\Rightarrow\ m=\dfrac{\frac{-3}{30}}{\frac{1}{4}}=\dfrac{-2}{5}[/tex]
Put the value of m in the general intercept equation , we get
[tex]y=\frac{-2}{5}x+c[/tex]
Put [tex]x=\frac{-1}{2}[/tex] and [tex]y=\frac{-2}{15}[/tex] in it , we get
[tex]\frac{-2}{15}=\frac{-2}{5}\times \frac{-1}{2}+c\\\\\Rightarrow\ c=\frac{-2}{15}\times\frac{5}{1}=\frac{-1}{3}[/tex]
Hence, The slope is [tex]\frac{-2}{5}[/tex] and the y-intercept is [tex]\frac{-1}{3}[/tex]
Louise completed the work shown below.
(5x3 + 3)2 = (5x3)2 + (3)2 = 25x6 + 9
Determine if Louise’s answer is correct. Explain.
Sample Response: Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself. Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial. Louise also could have used the formula for a perfect square trinomial, which is found by squaring a binomial.
Answer:
Louise is missing the term [tex]30x^3[/tex]
Step-by-step explanation:
Remember that the formula for squaring a binomial is:
[tex](a+b)^2=a^2+2ab+b^2[/tex]
Where
[tex]a[/tex] is the first term of the binomial
[tex]b[/tex] is the second term of the binomial
Our binomial is [tex](5x^3+3)^2[/tex], so [tex]a=5x^3[/tex] and [tex]b=3[/tex].
Replacing values
[tex](5x^3+3)^2=(5x^3)^2+2(5x^3)(3)+3^2[/tex]
[tex](5x^3+3)^2=5^2x^6+6(5x^3)+9[/tex]
[tex](5x^3+3)^2=25x^6+30x^3+9[/tex]
Since Louise’s answer is [tex](5x^3+3)^2=25x^6+9[/tex], we can conclude that she is missing the term [tex]30x^3[/tex]
Answer:
Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself. Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial.

solve for x cos90=4/x
Final answer:
The equation cos(90°) = 4/x has no solution because cos(90°) is 0, and no value of x would satisfy the equation 0 = 4/x.
Explanation:
The student's equation is cos(90°) = 4/x. Knowing that the cosine of 90 degrees (or π/2 radians) is 0, we can substitute that into the equation, which simplifies to 0 = 4/x. This indicates that there is no value of x that would satisfy this equation, as no number multiplied by 0 can result in 4. Therefore, the solution is that there is no solution for x in this equation.

factor completely x^3 + 1/8
Answer:
((2 x + 1) (4 x^2 - 2 x + 1))/8
Step-by-step explanation:
Factor the following:
x^3 + 1/8
Put each term in x^3 + 1/8 over the common denominator 8: x^3 + 1/8 = (8 x^3)/8 + 1/8:
(8 x^3)/8 + 1/8
(8 x^3)/8 + 1/8 = (8 x^3 + 1)/8:
(8 x^3 + 1)/8
8 x^3 + 1 = (2 x)^3 + 1^3:
((2 x)^3 + 1^3)/8
Factor the sum of two cubes. (2 x)^3 + 1^3 = (2 x + 1) ((2 x)^2 - 2 x + 1^2):
((2 x + 1) ((2 x)^2 - 2 x + 1^2))/8
1^2 = 1:
((2 x + 1) ((2 x)^2 - 2 x + 1))/8
Multiply each exponent in 2 x by 2:
((2 x + 1) (2^2 x^2 - 2 x + 1))/8
2^2 = 4:
Answer: ((2 x + 1) (4 x^2 - 2 x + 1))/8
[tex]x^3+\dfrac{1}{8}=\\ \\ =x^3+2^{-3} = \\ \\ =x^3+(2^{-1})^3 =\\ \\ = (x+2^{-1})(x^2-2^{-1}x+2^{-2}) = \\ \\ = \Big(x+\dfrac{1}{2}\Big)\Big(x^2-\dfrac{x}{2}+\dfrac{1}{4}\Big)\\ \\ \\ \boxed{a^3+b^3 = (a+b)(a^2-ab+b^2)}[/tex]
these figures are similiar. the area of one is given. find the area of the other
Answer:
18 in²
Step-by-step explanation:
Given 2 similar figures then
linear ratio = 9 : 12 = 3 : 4
area ratio = 3² : 4² = 9 : 16
let the area of the other figure be x
[tex]\frac{9}{x}[/tex] = [tex]\frac{16}{32}[/tex] [ [tex]\frac{ratio}{corresponding area}[/tex] ]
cross- multiply
16x = 288 ( divide both sides by 16 )
x = 18
Area of other figure is 18 in²
The area of two similar figures is related by the square of the ratio of their corresponding sides. Once you know the ratio of their sides, you can find the area of the second figure by squaring this ratio and multiplying it by the area of the first figure.
Explanation:To figure out the area of the second figure, first you need to understand the concept of similarity. Two figures are similar if their corresponding sides are proportional. When two figures are similar, the ratio of their areas is the square of the ratio of their corresponding sides. If we let's say the ratio of their corresponding sides are in the ratio 1:R, then the ratio of their areas would be 1:R^2.
Suppose the area of the first figure is A and you're looking for the area of the second figure (let's call it A'). If the sides are in ratio 1:R, then A/A' = (1/R)^2. Or conversely, A' = A * R^2.
Once you find R (the ratio of their corresponding sides), you can find the area of the second figure by multiplying the area of the first figure by R^2.
